GIS in the 1700s! Indiana's Historic Land Record Field Notes Digitized into Online Maps
Thursday, April 22, 2021, 2:00 PM - 3:00 PM EDT
Category: Webinars

Cosponsored by IGIC and the Indiana State Library


The Historical Land Survey Records - Marion County Pilot Project goal was to research, locate, digitize, process and make publicly available the four versions of the historical General Land Office (GLO), land survey field notes and plats, using a Geographic Information System (GIS), a web-based mapping system. The current Phase 2 project focuses on a newly found source of the Original field notes (one of the four sets) that cover areas throughout Indiana.

The land records, field notes from the late 1700's to mid-1800's, are the basis for the current Public Land Survey System (PLSS) and describe land that was subdivided and is the basis for describing property parcels today. The Original GLO land survey field notes and plats were used to transcribe the three sets of field notes for the Federal, State, and County governments. Document transcription errors were found, and this resulted in the need for comparisons of the four sets of field notes. The Indiana State Archives staff have been integral in this process. The Phase 1 field notes are accessible from a digital map by clicking a PLSS township/range.
